A polyp that arises from the colon. It is characterized by the presence of serrated glands and the absence of generalized dysplasia. Some authors have suggested that it is a precursor lesion for some colonic adenocarcinomas with microsatellite instability. The disease is MONDO_0006156 (colon sessile serrated adenoma/polyp). Also known as: colon SSA, colon SSA/P, colon SSP, colon sessile serrated adenoma, colon sessile serrated polyp.
